The same principle applied outside the armed forces. Carver had never been on a job, even the ones that seemed beyond all justification, that someone, somewhere didn't believe was the right thing to do. He'd fought a man who was willing to bring down the wrath of God upon the world and provoke the end of days in the sincere and absolute belief that this was the road to salvation. Granted, he was crazy. But his conviction was no less total than that of men who'd claimed to be sane.
So now he didn't think about anything as he swam just beneath the surface of Currituck Sound, aside from the immediate, practical realities of his situation. He had several hundred yards to cover, through water that was virtually tideless, so currents were not a problem. The wind, now freshening once more, was against him, making the surface choppy. Although that slowed him down a little, he was virtually submerged, and the broken water surface only helped hide him from anyone watching from the shore. But having just overcome the threat of hypothermia, his biggest problem now was heat. His flying suit was acting as a dry shell-suit, but the multiple layers of undergarments essential to keep him alive at high altitude were putting him in danger of overheating. The process would begin with the swelling of his hands and feet, moving on to cramps and heatstroke, which could leave him disoriented, hallucinating and even comatose.
For SBS operatives, who regularly have to shift from the extreme cold of, say, an underwater drop-off from a submarine to the intense exertion of a long swim, followed by a climb up a ship's hull or oil platform, heat is a familiar adversary. So Carver took the swim slowly, regularly pausing to get his bearings and keep an eye out for hostile vessels. He presumed that the Coast Guard would be patrolling the sound, in the knowledge that al-Qaeda had made deadly attacks on US forces by speedboat before and might easily do so again.
Sure enough, he twice heard the rumble of screws in the water. There was nothing to do but stop swimming and remain as still as possible, treading water just enough to prevent himself sinking, with his snorkel-tube just an inch or two above the surface of the water. The first time, the cutter passed by a good hundred yards away. The second time the deep rumbling in the water intensified until Carver knew it was headed directly for him.
His eyes desperately widened to catch any scrap of light, he peered out into the black, murky water and then, suddenly, there it was, a foaming mass of bubbles streaming from the onrushing grey blade of a ship's bow. Carver took one last breath and dived, frantically kicking out with his fins as he fought to escape the inexorable avalanche of steel now bearing down upon him.
It was no good. He wasn't getting away. The bow was going to hit him. And then, just as he braced himself for the impact, an unseen force picked him up and flung him sideways, displacing him along with the water being forced away from the ship and he was caught up in the wake as it flowed away from the hull, and then, like iron filings attracted to a magnet, was drawn back towards the vessel.
Carver was hurled towards the flank of the cutter. He saw the diagonal red, white and blue stripes painted on its side and aft of them the words 'US COAST GUARD' printed in white capital letters. He hit the hull just under the final 'D', taking the blow on his left shoulder, arm and hip with a force that knocked the breath from his body, before the current swirled away again and left him bobbing in the open water as the stern of the cutter disappeared into the night.
Carver ran his hand over his body, pressing with his fingers to detect any broken bones. He felt shaken up and bruised, but his arm was still mobile and his chest only ached when he breathed, without the sharp, stabbing pain of a broken rib. He was fit to go on.
Fifteen minutes later, he was treading water beneath one of the two L-shaped walls that stretched out from the shore to form the dock. The entire structure was about sixty feet wide and twice as deep. Right next to Carver, facing out to sea, was a gap in the wall, about thirty feet wide, to let boats in and out. A man dressed in black fatigues, with a black flak jacket, boots and cap, was patrolling the wall on the far side of the gap, walking to and fro, pausing every so often to raise his night-vision binoculars and look out over the water.
Through the opening into the dock, Carver could see a yacht, moored to a floating pontoon at the foot of the far wall, its bow pointing towards him. This must be the Lady Rosalie, a 42-foot sloop loved by the President almost as much as the wife after whom she was named. He took a deep breath, dropped beneath the surface of the water and started swimming towards her.
Carver surfaced on the far side of the bow, in the narrow gap between the hull of the Lady Rosalie and the wooden planking of the pontoon floating beside her. At the far end of the pontoon a set of stone steps marched diagonally up the side of the dock wall. Still staying below the level of planking, Carver made his way along the hull. He ducked behind the yacht's stern, breathed deeply once again and dropped below the surface of the water. A good sixty seconds passed before he reappeared and looked back along the hull towards the guard. He had walked out along the wall, his back was turned and his attention was now focused out to sea. Still in the water, Carver pulled off his mask, snorkel and flippers. He pulled himself out of the water on to the dock and scurried across to the steps.
Crouching in the shadows, he reached into the pack on his chest and removed the Heckler and Koch. It was compact and snub-nosed, little more than a foot long, but plenty big enough for the job he would ask it to do.
Carver closed his eyes, regulated his breathing until it was slow and easy. His mind was running over the plans he'd memorized of the grounds of Lusterleaf, and the main house itself, no more than a hundred feet away across the grass that ran up to the dock. About twenty feet shy of the house ran a low stone wall, with a flower-bed in front of it, and a stone terrace behind, furnished with tables and chairs, that ran up to the back of the house.
Carver assumed that there were lookouts on the roof of the house. He also took it for granted that there would be agents inside the building, and that the lawn would be covered by motion-detectors, pressure-sensors and cameras with thermal-imaging capacity. There was no way he was going to get across that open space undetected. He just had to get across it fast.
The way Carver looked at it, the odds weren't really too bad. It would take less than four seconds to cross the open grass, hurdle the wall and get to the building. The man on the dock wasn't likely to pick him up straight away, and even if he did, he would have to be damn good to hit a running man from where he was standing. The agents up on the roof would be hampered by basic geometry. They would have to shoot downwards, and the closer he got to the house, the tougher that shot would become. And again, they would have to react with remarkable speed.
There were two possible ways into the house from where he was positioned: French windows leading into the main living-room and a back door by the kitchen. If Carver could get to either of those entrances, blast them open and then start shooting, he backed himself to take down anyone he met inside, including Lincoln Roberts.
So he crouched by the foot of the steps, as tense as a sprinter on the blocks, took three deep breaths, then sprang upwards over the stone and on to the grass. And then he just ran like hell.
Carver didn't need Einstein to tell him that time was relative. Four seconds feels like a lifetime when it only takes a fraction of one of them to trigger the alarm system that sets bells ringing and lights blazing… and suddenly you feel as if you're running through treacle. Warnings are being shouted from all directions. Guns are being raised. You're trying to jink and swerve to unsettle the shooters, but every sidestep only slows you down. Then the firecracker explosions of small-arms fire rip through the screaming of the alarm bells, and you wait for the first bullet to tear your flesh, but none comes, and then you just throw yourself the last twenty feet, and…
